OCO-2 is NASA's first mission dedicated to studying atmospheric carbon
dioxide, the leading human-produced greenhouse gas driving changes in
Earth's climate. OCO-2 will provide a new tool for understanding the
human and natural sources of carbon dioxide emissions and the natural
"sinks" that absorb carbon dioxide and help control its buildup.

After launch, an OCO-2 post-launch news conference will be held at
Vandenberg. Observatory and mission officials will provide the
spacecraft status and discuss its state of health.
